COMBINED SLEEPER AND CHAIR FOR RAILWAYS.

SPECIFICATTON forming part of Letters Patent No.362,787, dated May 10,1887.

Application filed November 16, 1886. Serial No. 219,013. (No model.)

Patented in England January 1, 1885, No. 11, and in Belgium July 16,1886, No. 73,878.

To all whom it may concern.-

Be it known that l, JAMES RILEY, a subject of the Queen of Great Britainand Ireland, and a resident of Glasgow, in the county of Lanark,Scotland, have invented certain Improvements in Combined Sleepers andChairs for Railways, (for which I have obtained a British patent datedJanuary 1, 1885, No. 11, and a Belgie patent dated July 16, 1886, No.73,878,) of which the following is a specification.

My said invention consists in making combined sleepers and chairs forrailways in an improved manner out of steel or wrought-iron plates, thejaws of the chairs being formed of part of the metal of the platesuitably shaped and folded or doubled, and each jaw having outer andinner thicknesses continuous with each other and with the middle part ofthe sleeper, while the lateral parts of the sleeper adjacent to each jaware separated by slits, and are also folded or doubled, as hereinafterdescribed, and as shown in the accompanying drawings.

A plate is first rolled of a suitable length and width, of a flat ornearly flat form and uniform section, or of a channel-shaped sec-' tion,or of any other suitable section, and the shaping is effected bystamping or pressing processes in which suitable shapingdies are used.The sizes of the chair-jaws in the di rection of the rails aredetermined by slits formed parallel to the sides of the sleeper beforethe corrugations are formed and folded, and the parts of the metal atthe outer sides of these slits are folded down upon the sleeperplate andserve to strengthen it near the chair part. The plate is neXt subjectedto a pressing or stamping operation, whereby the inverted-trough-likeform is given to it, the sides being bent downward, while the ends areby preference made to assume a splayed form, to give more bearingsurface011 the ballast. The bottom of the chair part, between the jaws, may, ifnecessary, be strengthened by the metal being originally rolled of extrathickness at that part. The steel and iron used in forming the combinedsleepers and chairs is heated, if necessary, preparatory to undergoingany of the shaping processes. The chairjaws may be shaped to suit thedoubleheaded or I rail or to suit the fiat-bottomed or Vignoles rail.

Figure 1 of the accompanying drawings is a plan of one end of a platefor forming a 00111- plete transverse sleeper with two chairs. Fig. 2 isa plan of one end of a completed sleeper with a chair formed on it, Fig.3 being a sectional elevation corresponding to Fig. 2, but with anI-section rail and the key shown in position. Fig. 4 is a plan showing amodification of the lateral parts of the sleeper, and Fig. 5 is asectional elevation showing a sleeper with the chair adapted for aVignoles rail.

A plate of a suitable size, and which may be of uniform thickness, hasfour slits, 0, made through it at each part at which a chair is to beformed, as shown in plan in Fig. 1, and then the parts, D, between theslits are by suitable dies and compressing apparatus bent and doubled toform the jaws J of the chair, as shown in plan in Fig. 2 and insectional elevation in Fig. 3. The parts E F at the outer and innersides of the parts D are brought closer together in the shapingprocesses, and the lateral parts G are folded or doubled in the mannerindicated in Figs. 2 and 3; or the parts G may be cut across, asindicated by the dotted lines H in Fig. 1, and then the parts betweenthelines H may be placed over and riveted upon the parts which areoriginally outside of those lines, but brought together during theshaping processes. This modification is shown in Fig. 4.

Either complete transverse sleepers each with two chairs, or bowl orpet, or other detached sleepers each with a single chair, may be madeaccording to my invention.

I claim as my invention- 1. A combined sleeper and chair of plate metalhaving the outer and inner thicknesses of each chair-jaw continuous withthe middle part of the sleeper and with each other, and having thelateral parts of the sleeper adjacent to each jaw separated by a slitand doubled or folded over, substantially as set forth.

2. The herein-described method of making combined sleepers and chairs ofplate metal, said method consisting in first making longitudinztl slitsin the plate on each side of the parts which are to form the chairs,then bend- 5 ing up and doubling the parts between the slits to form thejaws of the chairs, and then doubling or folding over the parts outsidethe slits, all substantially as set forth.

In testimony whereof I have signed my name to this specification in thepresence of [0 two subscribing Witnesses. r
